Part Number: UCC28713 Hello there,
Me and my team have designed a flyback supply based on the UCC2871x Controller. The supply is supposed to deliver 36V (main/controlled winding), and 12V from an additional winding. The output power is approximately 35W…
Sorry for the delayed response. Please see my answers to your questions below:
1. While not designed for 75VAC to 275VAC, this design will still operate across that range.
2. The output voltage can be adjusted by changing the value of R9. A smaller…
Part Number: UCC28700 Other Parts Discussed in Thread: UCC28713 , , PMP10200 I'm using TI WEBENCH for a DC/DC converter based on UCC28713.
The WEBENCH is limited to minimum Vin of 85Vrms / 90Vdc – is it limitation of the controller?
I do see…
Part Number: UCC28713 Hello and thank you for your support,
In reference design PMP10351 there is Transformer T1 which is not specified and I can not find that part number. There is part number G144071LF from GCI Technologies but something is wrong with their…
Other Parts Discussed in Thread: PMP4390 Hello TI Team,
I would like to use the PMP4390 reference design ( UCC28713 controller).
Could you provide the Altium readable design files?
Thank you and I look forward to your response.
Thanks for the additional information. I would suggest taking a look at one of the UCC2871x flyback controllers. The DC input UVLO can be set by the VS resistors in this controller family
Other Parts Discussed in Thread: UCC28720 Dear TI people, Regarding the parameters tON(min) and tDMAG(min). For the UCC28720 a tON(min) specification is given of 300 ns and tDMAG(min) of 1.2 us. My first question is: Does the calculated value for tON(min…
